It all depends on the species and hunt area. That geographic region encompassing Antelope 73, Deer 34, and Elk 120 is limited quota (i.e. draw). There may occasionally be extra doe/fawn or cow/calf tags available, depending on populations.

Nonresident application date for elk closes Jan 31st each year. I believe Deer and Antelope both close May 31st. Any leftover tags can be applied for starting June 19th, but according to WGF's website, there are no leftover tags in any of those three species' hunt areas as of today.

Depending on how much land your friend owns and whether she's a promoter of hunting or looking to thin down some crop damage, she might consider contacting the Regional Office in Casper about enrolling in the "AccessYes" program, or there's always word-of-mouth. If she's just looking to make some money, she's probably better off finding an outfitter to lease the hunting rights from her.
